| 中文摘要: |
| 不良地质体是影响工程建设安全的主要地质灾害隐患，为查明拟建德余高速公路石阡段内的不良地质体成因类型及分布位置，采用高密度电阻率法，针对典型平台布设3条测线，探测结果查明了勘查范围内的电性结构特征，分析该区复杂的地质构造活动并推测各地层的完整形态，同时圈定了不良地质体的分布位置与大小，并结合钻探资料分析了勘查范围内的不良地质体主要为岩溶裂隙及溶蚀构造，并对其稳定性进行了评价，为高速公路的生产建设安全、减灾防灾等基础处理提供了地球物理技术支撑。 |
| 英文摘要: |
| Unfavorable geologic body is an important hidden geological hazard affecting the safety of engineering construction，high density resistivity method is used to find out the distribution location and genesis of the unfavorable geological body in Shiqian part of Deyu expressway，three survey lines were laid out for the typical platformAs a result，the electrical structure characteristics was found out in the working area，the complex geotectonic activity was analyzed and the complete situation of each layer was inferred，meanwhile the distribution position and size of unfavorable geological body is determinedWith the drilling data，it’s analyzed that the unfavorable geological body in the working area mainly are karst fracture and dissolution structure，the stability was also accessed，it will provide geophysical technical support for the safety of expressway production and construction |
